SUBFAMILY PELOROPEODINAE ROBINSON, 1970a: 56

Genus CHRYSOTIMUS Loew, 1857a

CHRYSOTIMUS Loew, 1857a: 48 . Type species: Chrysotimus pusio Loew [Nearctic], designation by Coquillett, 1910c: 524. Listed in Sympycninae by Foote et al. (1965).

NOTES: Chrysotimus is known from all realms except the Afrotropical. Despite its wide distribution, this genus comprises only a small number of species. Chrysotimus is most diverse in southern temperate forests of

Australia, New Zealand, and Patagonia,

where it is often abundant. Many species await description from these regions. Species of Chrysotimus are generally found on vegetation, especially on broad­leaved trees.
